| Zusammenfassung: | The commonly used direct and indirect methods for calibrating detectors against a PRT have been discussed and generalized for realistic neutron fields which are produced using spatially-extended targets and an anisotropic production reaction. The gas target using the D (d,n)3 He reaction has been studied as an example of a realistic source. The influence of the entrance toll and the reaction gas have been considered. The correction due to first-order elastic multiple scattering from target material has been implemented. It could be shown that systematic errors of up to 5,5% can be avoided by the use of the new program as compared to the present standard procedures. |
